Title: High-speed motor
Inventor: BAN ITSUKI
IPC: H02P7/00
Filed: 1992-02-05
Abstract: PURPOSE:To save power elements by inserting switching elements for exciting control, into both ends of armature coils. CONSTITUTION:Magnetic poles 16a-16f are arranged at equal angle intervals with the width of 180 degrees. Armature coils (EC) 17a, 17d are jointed in series or in parallel with each other, and the jointed body is set to be an EC 32a. ECs 17b, 17e and ECs 17c, 17f are also set to be ECs 32b, 32c, in the same manner. Into the lower ends of the ECs 32a-32c, switching elements (Tr) 20a-20c are inserted. Now, at the time of exciting the EC 32b, because of the charged high voltage of a capacitor 41b, the rise of armature current is turned quick. Then, salient poles 1b, 1f are attracted, and a rotor 1 is rotated by 120 degrees in the direction of an arrow head A. After that, when the electrification of the EC 32b is stopped by the Tr 20b, then by stored magnetic energy, due to a diode 49b, the capacitor 41b is kept with charged high voltage, and current fall is turned quick. After that, in the same manner, by every rotation of 120 degrees, the ECs 32a, 32b, 32c are exchanged with each other.

Filed: 1987-03-18
Abstract: PURPOSE:To precisely measure the shift quantity of the threshold voltage of a memory transistor by outputting an input voltage impressed on the input terminal of a test mode signal generation circuit as a test mode signal. CONSTITUTION:The input voltage 30 impressed on the input terminal of the test mode signal generation circuit is outputted as the test mode signal TE. Therefore, the maximum value of the voltage for a test mode restricted by the transistor controlled by the test mode signal TE can be set at a high level. Thus the shift quantity of the threshold voltage of the memory transistor can be precisely measured by impressing the voltage for the test mode higher than the threshold voltage of the memory transistor on a control gate.

Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To provide a unitized building which prevents a partitioning wall from being thickened, and is equalized in rigidity of the entire building, and to provide a method for assembling the unitized building. SOLUTION: There are provided standard columns 41A each isolatedly arranged at a projected corner 1A of a unitized building 1, and small cross-sectional columns 41B to 41D each having a smaller cross section than that of the standard column 41A. When these small cross-sectional columns are bound to each other, the entire peripheral dimension thereof is almost the same as that of the standard column 41A. Each of the gathered small cross-sectional columns 41B to 41D is smaller in cross section than the single standard column 41A, and therefore the rigidity of the gathered small cross-sectional columns is smaller than the rigidity of the plurality of standard columns 41A which are gathered and bound to each other, so that the rigidity of the small cross-sectional columns approaches the rigidity of the single standard column 41A.  As a result, the balance in rigidity of the entire unitized building 1 can be achieved.

Title: Event information processing system
Inventor: TAKESHITA SATORU
IPC: G06F9/46
Filed: 1990-03-15
Abstract: PURPOSE:To attain the normal processing even if an event control part is inactive by inquiring of a mediator about the address of the even control part via a synchronous part, waiting for the answer of the address to be given from the mediator, and transmitting an event information message to the address if obtained. CONSTITUTION:The synchronous part 11 inquires of a mediator 4 about the address of an event control part 6 and waits for the answer of the address to be given from the mediator 4. When the part 11 receives the address from the mediator 4, the part 11 transmits an event information message to the address. Therefore the outgoing origine of the even information message can carry on the normal processing even if an event to be informed to the part 6 occurs before the part 6 is started. Furthermore, the message is delivered to the part 6 after the part 6 is started. Thus, the necessary processing is carried out at the part 6. Thus, it is not required to stop the operation of a system nor to load again an initialization program.

Title: Production of magnetic disk substrate
Inventor: OIKAWA YASUO
IPC: G11B5/84
Filed: 1988-03-18
Abstract: PURPOSE:To decrease warpage deformation and to obtain desired surface roughness by using an unsatd. polyester resin which is a thermosetting resin as a binding medium of a resin compsn. and heating and pressurizing the same between flat plates at a specific temp., thereby correcting the warpage. CONSTITUTION:The unsatd. polyester resin having <=100 deg.C glass transition temp. Tg is used as the binder and is subjected to heating and molding by using the resin compsn. contg. an inorg. filler. The molding is thereafter held in place between the flat plates and is heated to the temp. above the glass transition temp. of the resin and below the heating temp. at the time of the molding. A pressure is exerted between the flat plates to shape the molding. The substrate exhibits a soft rubber-like state and the micro Brownian movement of the molecules is in the active state if the molding is pressurized and heated under such conditions. The warpage deformation generated from the external stresses generated by the molding conditions is, therefore, easily corrected. However, the resin is too hard and brittle and in addition, the warpage correcting temp. increases and there is the possibility of generation of thermal deterioration if the Tg is too high. The resin having <=100 deg.C Tg is consequently more preferable.
